Lifeline and Sun Xtender AGM Batteries –True Deep Cycle Superior to Every Deep Cycle GEL Battery on the market
There is just nothing like it in the world. Many claim to have it, but Lifeline® and Sun Xtender® Batteries by Concorde® are truly in a class all their own. The proprietary AGM deep cycle Batteries from Concorde under the Lifeline® and Sun Xtender® names far outperform gel batteries in the following ways:
1. Energy density - Power
a. capacity per pound – less electrolyte leads to less weight
i. AGMs are lighter - only electrolyte to saturate the matting
1. Mats filled with capillary action
2. Electrolyte held in place
ii. GEL Batteries are heavier – full of electrolyte
1. Under high heat, the electrolyte liquefies
2. Silica based gel
iii. It is much easier to fill a container with a liquid versus a semi-solid.
1. AGM batteries require less space between plates,
2. Reduces the internal connection length
3. Increases the lead density.
a. AGMS are leakproof, no leaks inverted under multiple G forces and heavy discharge / charge
i. Products test to Navy, Air Force, and Army Specifications
ii. Quality - Hand Made in the United States
b. DOT Shipping Exempt: Fedex, UPS, & USMail
3. cycle life, charge and discharge routines
a. Graph is of published Data
b. As gel batteries age the semi-solid electrolyte shrinks and dries out.
i. Leads to shorts and plate failure
ii. Shortens cycle life of the battery
c. Sun Xtender® & Lifeline AGM batteries have the microporous glass mat separator holding the liquid electrolyte like a sponge,
i. shrinkage of the electrolyte does not occur.
ii. Capillary action keeps the plates “wet”
4. vibration and shock tolerance.
a. “Packed” AGM design necessary for capillary action
b. Packing manner retards vibration
c. AGM not prone to air pockets like GEL Batteries
These AGM deep cycle batteries are more forgiving in overcharge conditions than their gel counterparts, and its ability to recombine the hydrogen and oxygen gases back into water is more efficient, recombination rates tested better than 99%.
AGM Battery Charging is not limited
Concorde has tested its AGM batteries to find out the effect on cycle life by overcharging. Their standard recommendation for charge voltage is 14.2 to 14.4V [2.37 to 2.40 V/cell]. AGM batteries are able to absorb charge quickly, without going into a “Thermal Runaway”. Feel free to charge batteries at high amperages, so long as the voltage is regulated at 14.2-14.4 volts at that amperage. Watch out for voltage loss due to wire length at high amperages. Over charging due to a high finishing voltage (low amps) will cook the battery in the final stages if the bulk stage is tuned to 14.2-14.4 volts for high amp output.
AGM Batteries love a 3 stage computerized charging regimen. It helps to thoroughly break down the chemicals inside the battery to their original state. However, tried and true charging stages of bulk, and float will do fine if the voltage is regulated.
Gel batteries are not able to handle high rate charging.
Concorde Gel Battery History
Concorde Battery Corporation has had years of experience manufacturing quality gelled electrolyte batteries trade named “Gel Power®” before developing the AGM battery technology for Lifeline & Sun Xtender® Series batteries. This puts them in the unique position of understanding gel’s inherent limitations. Concorde is still the only AGM battery manufacturer with a true deep cycle battery with thick plates.

OUR DENVER WAREHOUSE IS MOVING TO A NEW LOCATION AT THIS TIME.
WE WERE SCHEDULED TO REOPEN OUR BRICK AND MORTAR BATTERY WAREHOUSE IN EARLY 2011.
IN THE MEAN TIME OUR WEBSITE AND PHONES OPERATE FINE!
We do thank the public for the outreach of concern, and votes of confidence.
Do call Lorene prior to schedule used battery pickups, new battery dropoffs, etc. by appointment.
